This invention relates to tabulator cards or sheets for use with accounting or tabulating machines, the several operations of which are effected by means. of index points on the tabulator records. Prior to this invention, it has only been known to use index pomts differentiated from each other by varying their position in the record field. 7

These index points have generally been in the form of perforations, necessitating a spe-' cial punching operation on the records previous to their use in the accounting machine. The interpretation of normal written data onto a record thus required a separate operation which had to be carefully checked for.

accurac by one acquainted with the particular co e used to interpret the written data. The records after having the data perforated thereon according to a certain code were adapted to be separated into groups by means of a sorting machine. Usually, these groups of records, after sorting, were placed in an accounting machine wherein means, controlled b I each card of the group individual- 1y, accumulated the totals ofthe several records, listed the successive totals, and printed the total after listing.

.The object of the present invention is to provide record means other than perforations for efiecting controlling operations of a sorter, tabulator, or the like, By means of this invention, the control is efiected directly by graphic indications, which may control the machine by varying the contour or form of the written character so that it covers a combination of basic or code points in a standard record field.-. In; this case, the character controls the tabulating operations by actuating an analyzing means according to the combination of points corresponding to each character. ThlS analyzin means may be a wave controlled means, suc as a plurality of light sensitive. cells, preferably potas-' sium cells, for analyzing the character field,

at its several code points.-

Tl-e controlling characters, accordin to this invention may also be differentiated 1n each other by varying the proplortion of the record field CL vered by the c aracter. In the lat er case, this invention provides only i when figure 4 is under the analyzing light.

one light sensitive cell for, analyzing the character field at its several code points.

The controlling characters, according to this invention may also be diiferentiatcd from each other by varyin the proportion of the record field, covered hy the character. In the latter case, this invention provides only one light sensitive cell foranalyzing v the character field. I

The object of this invention is, further, to do away with the necessity of havin a definite position in the record field to enote a character. The characters are positioned, according to the present invention, re ardless of their si ificance as characters. 11 other words, a c aracter will have thesame efiect no matter where it is located on the record.

Another object of this invention is to have index points in the same position of the record fields cause different operations of the accounting machine. m The characters may be difierentiated from each other, according to this invention by varying any of their inherent physical c aractieristics, such as size, shape, area or mate- 1'18. Other objects of this invention will be disclosed and pointed out in the succeeding portions of the specification.

Fig. 13 shows a card with characters printed thereon in accordance with my invention.

Referring to Figs. 1, 2, and 3, the record card or sheet has a number of equal portions or fields 20, preferably alinedin a row, in each of which is printed, in accordance with the statistics to be tabulated, one of the figures 0-9' in heavy black type. If four imaginary points bearranged in each field as A, -B C and D, (see Fig. 21) then each figure when printed in the fiel will cover one or more of the points, depending on the contour of the figure. For example, character 0 will cover points A and D, leaving B and G exposed (as shown by the unprinted field below the printed figures where the black points are those covered and the white points those exposed) figure 1 will cover points B and C,

caving A and D uncovered; figure 2 will cover points A and C, leaving B and D uncovered; etc. Each fi ure will cover and uncover a different com ination of points thus providing a different code for each character as tabulated in Fig. 3. Now if a single record field be exposed as in 4 to a beam of ii ht, hereinafter termed the analyz-,

ing beam, irected at an angle from the source 21 through a lens '22, the rays of light will be reflected by the exposed or white surfaces of the record field and be absorbed by the black surfaces or figure printed on the field. The reflected rays will pass through a lens 23 which will direct them on a transparent plate 24 such as plate glass, thus reproducing on -said late an image of the record field. Below the plate, in a frame 25 are arrangedfour light sensitive cells '26, such as potassium cells, in the same order and position relative to the reflected field 27 as imaginary oints'A, B, C and D in the actual record-fiel Since the reflected field is dark in portions corre sponding to the character on the actual record field, thosecells which are directly under the dark portions will not be energized as represented by the black points of Fig. 1. For example, if figure 0 be'reflected on field 27, cells 26A and 26D. will not be energized while cells 26B and 26C will be exposed to the beam of reflected light and be energized. It is ofcourse understood that the form of the figure may be varied, that the number of cells may also be varied both in number and arrangement or either; that instead'of figures,

- letters or other characters may be used; and

that in each case, the printed character may be so shaped as to cover adiflerent combine-i onl operatin The adaptation of the invention to one form of. a tabulating machine is shown in Figs. 6 and 7. As is usual in tabulating machines for each record column or in this case record field is provided an individual anal 2- ing, accumulating and printing means. or the purpose of simplifying the explanation,

one such unit is illustrated and described. Thus Fig. 6 shows the mechanism to analyze, accumulate and print in accordance with the figure contained in one standard record field 20. The analyzing beam energizes cells 26 in accordance with the character code hitherto explained and the resulting current isamplified by units 31 to energize translating magnets 32, at a period in the cycle determined by cam 36 closing contacts 37. In this case the magnets '32 serve'to control the differential mechanism which actuates the accumulator'and printer in accordance with the analyzed figure.

Magnets 32, upon-energization t ereof in accordance with the code, attract armatures 44 linked with contact fingers 45 by means of rods 46. After actuation, thearmatures are retained in position by detents 47 which are moved to release the armatures at the end of the cycle by a bar 48 having lugs 49,.contacting the detents- Bar 48 is actuated by armature 50 attracted by magnet 51 when contacts 52 are closed at the end ot the cycle by a cam 53. A commutator 54 is provided with ten conducting segments 55, corres onding in succession to the digits 0 to 9. synchronism with the movement of t pe bar 56 is a pair of diametrically opposed brushes 57. In the rotation of the brushes, contact will first be made with, the segment corre= sponding to figure 0 then with the segment corresponding to figure 1, etc. Fi '7 illustrates the position of the contact gers 45 when figure 4 is analyzed. The code for fi ure 4 (see Fig. 3) results in energizing cel 26A and B, causing magnet 31A to move the contact finger 45A to close contacts 58A and magnet 31B to close contacts 58B. When-the brushes 57 reach the commutator segment 55 nism with the. rotation of the commutatorbrush 57. The manner in which the setting and operation of the type bar 68 controls the.

printing of the data and the accumulation of values is more specifically brought out in otating in U. S. Patent #1,780,685, to John Royden Peirce for Printing tabulating machines.

In Fig. 8 is shown a system of printing characters on a standard field which does away with the necessity of analyzing the field at predetermined basic points. The characters are differentiated from each other by varying their relative sizes, each character covering a different percentage of a standard field. If characters -9 for example be printed on the fields, they may be varied in area according to the percentages marked in Fig. 8. If the analyzing beam of light be directed with uniform intensity at all portions of the field, the quantity of light reflected toward the photo cell unit will 'be varied according to the area of the field covered by the character. In this system, only one photo cell is required for each analyzing mechanism which will have a current produced therein varying with the quantity of light reflected and consequently with the size of the character, Each character thus produces a different current in the hoto cell as illustrated by the dotted line in ig. 9 which also shows the gra h of the area covered by the characters of ig. 8, the intensity of the current var ing inversely as the area of the character w ich constitutes the black portion of the field.

In Fig. 10 is shown an adaptation of this system to a sorter for record cards. The rotating picker device 77 feeds-one card ata time from magazine 78 to a series of feed rollers 79 which conduct the card beneath a series of photo cells .80, one for each sorting pocket 81. The card field is illumined diagonally at each sortin station by an individual light source'82 Fig. 11). .The rays of light reflected from t e eld are concentrated by means offia converginglens 83 on the transparent plate 84 above which is the photo cell 80. The current in'the photo cell energizes a magnet 85 corresponding thereto to attract its armature 86 and raise deflector 87 to intercept the advancing card causing it to drop into the pocket 81. The magnet coil 85 for each pocket has a different number of ampere turns, the minimum number of turns being on the magnet in the reject pocket, taking care of blank fields, the next highest numberof turns on the magnet in the 0 pocket, and the'greatest number of turns on the magnet in the 9 pocket. The card passes successively through the reject sorting station, the 1 sorting station, the 2 sorting station, etc., in the order indicated. It is known that the magnetic attraction of a coil varies directly as the number of ampere turns. 'If, for example, Figure 5 is on the card field, it will pass successively under the analyzing cells for the reject 0, 1, 2, 3 and 4 pockets. The current .produced in any of these cell energizes the magnets. for'these pockets but the magnet field set up by the coils of these magnets is insufiicient to attract their armatures. When the card reaches the 5 analyzing cell, the number of ampere turns-of the magnet in the 5 pocket is sufiicient to attract the 5 armature and hence guidethe card into the 5 pocket. Tohold the armature in position till the end of the cycle, after actuation. a detent 88 is pro vided behind which the armature 86 sna s as soon as it is attracted. At the end 0 the cycle, a magnet 89 under control of cam 90 'c osing contacts 91, actuates detent 88 to release the armature 86. The current through the cells and the magnets is completed when the cards are in their proper osition in front of the photo cells by means 0% contacts 92.

It is apparent that in all the. above described machines, means are provided to prevent light not reflected by the card field from reaching the photo cells.

It is understood that the invention may be carried out in a great number of ways andby a variety of means. It is not necessary to utilize photo cells. or any other light phenomena' to translate the reading of the field. For example, an induction field may be used as an analyzing field and the characters in the card field be printed in ink havin metallic characteristics. Then if each 0 aracter has a different quantity of metal printing,

. the induction field will be varied by the passage of a character therethrough to control. mechanisms such as magnet coils or the like in' a manner heretofore indicated.

It is obvious that the records operated on by the machines described may be in the form of a card, a strip, a roll, or any other. form of device containing printed matter.

In Fig. 13 the record card A is shown with a'group of numerals A1. It will that these numerals cover varyin areas in accordance with the disclosure in ig. 8.
